Hi Lombardialess,
I watch the log when ESXi boots (alt+F11 or so) and yes, there are failures. But I think those are "left overs" from all my testing. When boot is done all LUNs are here. Acually they have allways been. But best is now that all vmks are now being used and I have all possible paths. For this to work the SAN has to be pingable to every IP. I do this from the host. If your pings don't work then you should check the cables or your network setup. How did you do this? IPs, how many pSwitchs, what SAN, how many ports?
Greetins,
Jerry
